Windows 11 fails to boot shortly after installation

[lazynooblet]

I've seen a few similar threads on this, but haven't got a solution that works for me yet.

I have a new host Proxmox host, and what I used to do before is now failing.

I am using Proxmox to test Windows 11 Autopilot builds. The Autopilot build doesn't do much fancy things, but it does join the device to Intune and enable Bitlocker. Windows 11 24H2 installs from ISO fine, it gets picked up by Autopilot during OOBE and I eventually get to a working desktop. However if I shutdown/reboot, on next boot the primary volume will be "RAW", causing "Automatic Startup Repair" to kick in and fail.

I am not passing through any hardware, its a simple Win11 capable VM.

Using the Win11 pre-boot recovery UI, I open command prompt and diskpart shows as "unknown", and chkdsk compalins it can't work on RAW devices



My process has been

1. Create Win11 VM
2. Add Win11 24H2 iso
3. Add Virtio iso (in this case virtio-win-0.1.266.iso)
4. Boot and install Win11
5. At first OOBE, create snapshot
6. Press SHIFT+ALT+F3 to boot into Audit mode
7. Install virtio drivers and guest tool
8. Reseal and boot back into OOBE
9. New snapshot
10. Enrol onto Autopilot using Get-WindowsAutopilotInfo.ps1 -Online
11. Complete OOBE, Autopilot then takes over
12. Eventually get to desktop, confirm device has enrolled correctly
13. Bitlocker is Fully encrypted
14. Reboot to test

However after the reboot, I will get the "Automatic Startup Repair" issue, with a broken volume.

I have tried so far to fix a broken VM

1. Adding ",hidden=1" to the cpu type
2. Using x86-64-v2-AES as cpu type
3. Using display driver Virtio-GPU
4. Disabling secure boot in VM bios
5. Switching from Virtio to SATA
6. Adding to VM args: -cpu Cooperlake,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time,+vmx

As I type, I am now trying again with x86-64-v2-AES as cpu type from the very beginning.
Edit: Build using x86-64-v2-AES CPU has same issue on first reboot.
Edit: Disabled bitlocker prior to reboot, same issue
Edit: Recreating VM using E1000 NIC and SATA disk, no virtio drivers, and an Autopilot build survives reboots. This fits my purpose, I don't carte about performance. But I'll look into this more and do more testing if I receive any updates here.

Any ideas/suggestions welcome.
